Technical Specifications and Features

This vented disc brake rotor features a straight vane design that promotes efficient airflow to reduce heat buildup during braking. The rotor’s nominal thickness of 1.654 inches (42 mm) and discard thickness of 1.535 inches (39 mm) provide a clear service limit to maintain safe braking performance. With a smooth surface type, the rotor ensures even pad wear and consistent braking feel. The 12 mounting bolt holes with a 5.354-inch (136 mm) bolt circle diameter and 0.480-inch (12.2 mm) bolt hole diameter allow for secure attachment behind the hub, matching specific vehicle requirements.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Upgrading from solid to vented rotors for improved heat dissipation
• Addressing rotor thickness below manufacturer discard limits
• Resolving uneven brake pad wear due to rotor surface imperfections
• Ensuring proper fitment for vehicles requiring 12-bolt mounting rotors

Installation Notes and Tips

Ensure the rotor is installed behind the hub as specified for proper alignment. Verify the mounting bolt hole pattern and center hole diameter match the vehicle’s hub assembly. Clean the rotor surface before installation to remove any protective coatings or contaminants. Use a calibrated torque wrench to tighten mounting bolts to manufacturer specifications to avoid rotor warping. This rotor does not include bearings or ABS tone rings, so verify compatibility with your vehicle’s braking system.
